In my mom and dad's house the sewer clean-out pit is bare clay. I measured a high of 120Bq/m3 ( for picocuries divide by 37) ten feet away. Finished basement 1980s no HVAC. I covered the pit temporarily with rigid foam insulation board and cardboard now it's down to 52 long-term and 38 short-term. My Dad died of IPF a lung scarring disease and it can be caused by radon exposure. He was a smoker early in his life I read about how the smoke particles and radon combination make it even worse.

Keep in mind the electronic radon meters last only a year if your lucky before they have to be recalibrated in a chamber!!! High radon is in hot and humid weather, when ground is saturated with water, frost etc ... A good radon company with good guarantee's charges on average for 2 hole basement pipe drop $1850.00 with a guarantee of 4 and below on radon readings and $2450.00 for 3 hole pipe drop with a guarantee of 2 and below reading of radon. Make sure the company you have installing the piping uses pvc CLEANER and pvc GLUE on all fittings and pipe!!!!

A credited company on the epa list for test kits is AirCheck. Easy hanging radon test kits.

I had high humidity in my crawl space. When I closed the vents I checked radon levels (after my former boss got lung cancer) The levels were high as our house is on rock. Had a Radon guy come in who sealed my crawlspace and installed a special pipe under the plastic then with a fan he vented it above my roofline. My Radon level now is 0.51 Pc/L I think it was 40 Pc/L before

I noticed during the warm season daily radon levels are higher in my basement than in the cold season

That makes sense. Most Gases are expansive

@kencarr5618 6 ай бұрын

The norm is higher in the colder months. Cold outside air pushes down through the soil and the stack effect in the home pushes radon up into the home.

What if you have a single-story gone with no basement but an underground in-garage storm shelter?

@burnsaga 8 ай бұрын

You kept saying 'basement' but radon exposure can still be an issue if you don't have a basement

Is this a larger issues in different locations? In the Northwest we barely hear about this

Yes. It is a regional thing.

There are EPA maps for each state showing the average radon levels per county broken down into 3 Zones of potential radon levels. Just because you live in a certain zone does not directly indicate the radon levels of your house, it is completely dependent on the geology below your house combined with the negative pressure your house creates. Houses or apartments right next to each other can potentially have drastically different radon levels. Only way to know for sure is to test.

I just had this put in our new house. Two crawlspaces piped together. $8700 total.

Do they finance

@Cravz69 5 ай бұрын

@@tonyzone8999 No idea, sorry. I try to pay cash for everything as it typically give the best price. In this case, they came down from $9300 to $8700. Worth it to me. The cheapest bid was just under 7K, but with cheaper material and not as good of a sealed installation. Hope this helps.

Seems like you got ripped off. $8700 for drilling a couple holes and installing some pvc pipe?

@Cravz69 5 ай бұрын

@@Atreid3s As I stated, I had lower bids, but I chose this one due to the higher thickness membrane, more thorough installation (sealing), and warranty. It’s worth my family’s health for a little more $, and it’s essentially capsulated now. We went from 8.0, to .0.3 in both crawl spaces. Money well spent.

So if I buy this kit will it save me from spending $160 for a professional raydon test?

@robertrocheville7769 2 ай бұрын

I think you would still need to do the lab side as well. $20 for the kit. I don't know what the charge is for the test itself.

Wait a minute. What you are saying is the fix is causing more radon to come into basement.

How long do these radon mitigation systems last? Or when does the fan need replaced? Mine is 13 years old. The fan is noisy, but still seems to work. Got a quote years back for $500 to replace the fan.

@robopaul9 10 ай бұрын

Buy a new fan (should be roughly $100 - $150). You can probably buy the same model. You can easily replace the fan yourself because radon mitigation systems are installed with the expectation to replace the fan in the future.

@@eagles5769 try a passive system first (without fan); you can always add the fan later if passive is not effective. I installed just the pipe in my basement sump vented it out and the pressure differences between outside and inside of house were sufficient to drive radon levels from 17 picoCuries/L to less than 2.0.
